Efficacy of a Combined Ergonomic Health Promotion Intervention on Employee Health

Our objective in this pilot study is to test the combined effect of a) replacing office workers' sedentary workstations with active workstations (LifeBalance Station) and b) optimizing computer workstation ergonomics on daily occupational sedentary time, cardiometabolic risk factors, musculoskeletal symptom health outcomes and work productivity.

About this study

Primary Aim: To compare the effects of providing sedentary employees with seated active workstations in combination with an ergonomic intervention and regular motivational emails (experimental group) against the ergonomic intervention and regular emails only (active control group) on occupational sedentary behavior over 16 weeks.

Hypothesis: The addition of a seated active workstation will result in significant reductions in daily occupational sedentary time compared to the active control group.

Secondary Aims: To compare the effects of the experimental group against the active control group on secondary measures of cardiometabolic disease risk factors, musculoskeletal discomfort, cognitive function and work productivity.

Hypothesis 1: The experimental group will result in reduced cardiometabolic disease risk, musculoskeletal discomfort and work limitations compared to the active control group.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • We will recruit overweight/obese (body mass index 25.0-40.0 kg/m2) adults (18-65 years) working in full-time (minimum 35 hours/week), sedentary (self-report sitting >75% work time) occupations at an independent work site.

Exclusion criteria

  • Working in an office that will not meet the space or electrical requirements of the active workstation, acute or chronic illness not under treatment of a provider, orthopedic limitations that prohibit physical activity, current or planned pregnancy, hospitalization from a physical or mental disorder in the past six months and/or taking medication that may impair physical activity

Treatment and study plan

Active Workstation Intervention

Behavioral

Participants in the experimental group will receive a seated active workstation at their work setting for 16 weeks.

Ergonomic Intervention

Behavioral

Participants of both arms will receive a face to face ergonomic workstation optimization intervention. This consultation will take 30 minutes to complete and will be performed at the participant's actual work station.

Email Intervention

Behavioral

Participants of both arms will receive three emails per week for 16 weeks. Messages will be consistent with what they hear in the ergonomic intervention (e.g., encourage taking breaks from sitting at work and adjusting posture to be in line with ergonomic principles).

Bluetooth enabled device (Wahoo Fitness Blue SC sensor) and accompanying iPod application.

Primary outcomes

  1. Change in Occupational Physical Activity From Baseline to 16 Weeks

    Time frame: Baseline and 16 weeks

    Occupational physical activity (primary outcome) will be measured objectively with the GENEActiv physical activity monitor. The monitor will be worn on the right ankle and will be worn for 5 working days during all non-bathing hours. The outcome measure will be change in occupational activity (average counts/work day) from baseline to 16 weeks. The measure will be calculated as follows: 16 weeks value - baseline value.
